Nutanix Prism

Basic Information

Nutanix Prism is a comprehensive management solution for the Nutanix Cloud Platform, serving as a unified control plane that simplifies and streamlines the management of all environments running on Nutanix. It consists of two core components: Prism Element (PE) and Prism Central (PC). Prism Element is embedded within every Nutanix cluster, providing local cluster management and operations. Prism Central is an optional, separate virtual appliance designed for multi-cluster management, offering a single-pane-of-glass view across distributed Nutanix environments, including hybrid and multi-cloud deployments.

• Model: Nutanix Prism (comprising Prism Element and Prism Central).
• Version: Nutanix Prism Central versions follow a `pc.X.Y.Z.n` format. Nutanix transitioned to a Unified 'NCI Release Model' with major or minor releases typically available every 6–9 months. Recent versions include `pc.2024.3.1` and `pc.7.3`.
• Release Date: Major or minor releases are typically made available every 6–9 months under the Unified 'NCI Release Model'.
• Minimum Requirements: For Prism Central, requirements vary based on deployment size (Small, Large, X-Large). A small Prism Central VM typically requires 4 vCPUs, 18 GB of memory, and 100 GiB of storage. A 3-VM scale-out instance can require 6 vCPUs, 28 GB of memory, and 500 GiB of storage. These resources are for the Prism Central VM itself, with additional resources needed for optional features.
• Supported Operative Systems: Prism manages virtual machines running on various hypervisors, including Nutanix AHV, VMware ESXi, and Microsoft Hyper-V. Prism Central itself is deployed as a virtual appliance.
• Latest Stable Version: As of recent information, `pc.2024.3.1` addresses known vulnerabilities, and `pc.7.3` mandates Microservices Infrastructure.
• End of Support Date: Under the Unified 'NCI Release Model', all major/minor releases are actively maintained with bug and security fixes for 15 months, followed by an additional 9 months of troubleshooting with only security fixes.
• End of Life Date: End of Support Life (EOSL) is the last date a product is entitled to receive applicable support. After this date, all support ceases unless covered by an active Extended Support contract.
• Auto-update Expiration Date: Not explicitly defined as a single expiration date; updates are provided throughout the maintenance period of each release.
• License Type: Licensing is typically tied to Nutanix Cloud Infrastructure (NCI) editions (e.g., Pro and Ultimate editions for advanced features like software-based data-at-rest encryption and native key management services).
• Deployment Model: Prism Element is built into every Nutanix cluster. Prism Central is deployed as a separate virtual machine (VM) or a scale-out cluster of VMs. It can be installed on a Nutanix cluster or in a non-Nutanix environment (e.g., ESXi).

Technical Requirements

Nutanix Prism Central, as a virtual appliance, has specific resource requirements that scale with the size and features enabled. Prism Element is embedded within each Nutanix Controller VM (CVM) and utilizes the cluster's resources.

• RAM: For Prism Central, configurations range from 18 GB (small) to 28 GB (3-VM instance), with additional memory required for optional features.
• Processor: Prism Central deployments typically require 4 vCPUs for a small instance, scaling up to 6 vCPUs for a 3-VM instance.
• Storage: Minimum storage for a small Prism Central VM is 100 GiB, increasing to 500 GiB for a 3-VM instance.
• Display: An HTML5-compatible web browser is required to access the Prism user interface.
• Ports: Key ports include 80 (redirects to 9440), 443 (HTTPS), 9440 (Prism UI access), 3205 (iSCSI data plane), 3260 (iSCSI control plane), and 9361 (Prism Element to Prism Central communication).
• Operating System: Prism Central runs as a virtual appliance, managing VMs on Nutanix AHV, VMware ESXi, and Microsoft Hyper-V.

Analysis of Technical Requirements

The technical requirements for Nutanix Prism are primarily driven by Prism Central, which acts as a centralized management plane. Its resource footprint is scalable, allowing organizations to deploy a configuration that matches their environment's size and the number of managed clusters and features enabled. The distinction between Prism Element (embedded) and Prism Central (dedicated VM) is crucial for understanding resource allocation. While Prism Element leverages existing cluster resources, Prism Central requires dedicated virtual hardware, emphasizing its role in larger, multi-cluster, and multi-cloud deployments. The reliance on standard web protocols and common ports ensures broad accessibility and integration within existing network infrastructures.

Support & Compatibility

Nutanix Prism offers extensive support and compatibility, designed to manage diverse hyperconverged infrastructure environments.

• Latest Version: Prism Central versions like `pc.2024.3.1` and `pc.7.3` represent recent stable releases, incorporating bug fixes and new features.
• OS Support: Prism provides unified management for virtual machines across Nutanix AHV, VMware ESXi, and Microsoft Hyper-V hypervisors.
• End of Support Date: Each major or minor release of Prism Central is actively maintained for 15 months with bug and security fixes, followed by 9 months of troubleshooting with security fixes only.
• Localization: The user interface is localized in Simplified Chinese, Japanese, and Korean.
• Available Drivers: Prism, as a management plane, does not directly use drivers in the traditional sense. It manages the underlying Nutanix Cloud Platform, which includes its own software stack and hypervisor (AHV), compatible with various hardware components.

Analysis of Overall Support & Compatibility Status

Nutanix Prism demonstrates strong support and compatibility, particularly through its ability to manage environments running different hypervisors from a single interface. This flexibility is a significant advantage for hybrid environments. The clear lifecycle policy for releases, including defined maintenance and support periods, helps organizations plan upgrades and ensures access to critical updates and troubleshooting. Localization support further enhances its usability in global deployments. The "one-click upgrade" feature is frequently praised for simplifying maintenance and ensuring environments remain up-to-date.

Security Status

Nutanix Prism incorporates robust security features to protect the managed infrastructure and data.

• Security Features: Includes Role-Based Access Control (RBAC) with granular permissions, auditing and logging of activities, SSL certificate management for secure communication, cluster lockdown capabilities, and automated updates for consistent security. It also integrates with Nutanix Flow for network segmentation and application microsegmentation.
• Known Vulnerabilities: Prism Central versions prior to `2024.3.1` were vulnerable to a stored cross-site scripting (XSS) attack (CVE-2024-12223). Past versions were also affected by Log4j vulnerabilities (CVE-2021-44228 and CVE-2021-45046). Nutanix regularly releases patches and updates to address identified vulnerabilities.
• Blacklist Status: No indication of Nutanix Prism being blacklisted.
• Certifications: Native software-based encryption is FIPS 140-2 Level 1 certified.
• Encryption Support: Supports AES-256 data-at-rest encryption using either self-encrypting drives (SEDs) or software encryption with a native local key manager (LKM) or external key management services (KMS) like KMIP/TCG-compliant servers and Azure Key Vault. Data-in-transit encryption is also supported within a Nutanix cluster.
• Authentication Methods: Supports multiple authentication methods including Active Directory, OpenLDAP, Common Access Card (CAC) authentication, SAML identity providers, and local accounts. Multi-factor authentication (MFA) can be leveraged through SAML-compliant identity providers.
• General Recommendations: Implement timely software upgrades, utilize strong authentication methods (including MFA), enforce granular RBAC policies, and leverage network segmentation features to limit attack surfaces.

Analysis of Overall Security Rating

Nutanix Prism provides a robust security framework with multiple layers of protection, including strong access controls, comprehensive auditing, and advanced encryption capabilities. The platform's integration with features like Nutanix Flow for microsegmentation further enhances its ability to secure workloads. While like any complex software, it has experienced vulnerabilities (e.g., XSS, Log4j), Nutanix actively addresses these through patches and updates. Adherence to security best practices, such as regular upgrades and proper configuration of authentication and authorization, is crucial for maintaining a high overall security posture.
